Question

Solve the inequality for u 20>u+8

Answer 1

u < 12

Explanation:

20 > u + 8 ( subtract 8 from both sides )

12 > u , then

u < 12

Answer 2

Explanation:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day!

We can solve this equation in one step, which is Algebra, I'll start solving the problem now.

Algebra

We can start by simplifying the problem,
`20>u+8`, we can subtract by 8 on each side to simplify the equation. I'll explain why afterwards.

`20>u+8\\12>u`

As you can see we've subtracted by 8 on both sides, the reason this works is because when we do something to one side, we must do it to the other, which keeps the equation balanced.

We can prove this works by picking a random number for
`u` from our simplified version. For this case, lets pick 11.

We can see that if we plug it in to the first unsimplified equation, it works perfectly fine:

`20>11+8?\\20>19`

We've proven that its correct.

So our final answer is
`u<12`.
